  • Teaching Resources
  • Class Activities
  • Financial Literacy


Dead Reckonings


Ron Doerfler journals about the technically elegant, but nearly forgotten, art of the mathematical sciences. The creative works he highlights can be modest in scope (say, an algorithm for calculating roots), or ingenious technical inventions of more general application.

Posts here are brief records of unusual things of this nature, supplemented with references and some amount of research. Any longer papers that emerge (particularly on mental calculation and antique scientific instruments) will be placed in Doerfler's main website area:


Common Core State Standards Initiative


Governors and state commissioners of education from across the country committed to joining a state-led process to develop a common core of state standards in English-language arts and mathematics for grades K-12. These standards will be research- and evidence-based, internationally benchmarked, aligned with college and work expectations and include rigorous content and skills.

The Common Core State Standards Initiative is a joint effort by the National Governors Association Center for Best Practices (NGA Center) and the Council of Chief State School Officers (CCSSO) in partnership with Achieve, ACT and the College Board. The NGA Center and CCSSO are coordinating the process to develop these standards and have created an expert validation committee to provide an independent review of the common core state standards, as well as the grade-by-grade standards.
